The call implied that Gov. Martin O'Malley, a Democrat, had already won his race against former Gov. Robert L. Ehrlich Jr., a Republican.

Henson was working as a consultant to Ehrlich's campaign when the robocalls were made.

Ehrlich's campaign manager, Paul Schurick, was convicted in December of four counts in connection with the call. Schurick was sentenced to home detention and community service last week.

In his first budget address to lawmakers, Democratic Gov. Tom Wolf laid out an ambitious $33.8 billion spending plan that raises taxes a combined 16 percent while slashing corporate and property taxes, restores cuts to education and wipes out the state's deficit.
